SARS-CoV-2 Omicron (B.1.1.529) variant: structural features, biological characteristics, impact on scientific research, general precautions and protective procedures; a systematic review

The SARS-CoV-2 mutations that have occurred have alarmed the entire medical community. Thus, global concerns have been expressed regarding the transmission, pathogenicity and immune evasion of the Omicron strain, which shares mutations with the variants of concern Alpha, Beta, and Gamma strains. Still, Omicron transmission has crossed numerous borders worldwide compared to other types of SARS-CoV-2. The number of confirmed cases has increased and is reappearing in India. Given the worrisome situation created by the Omicron outbreak, scientists and postgraduates have had to make decisions about current research programs at institutions around the globe. The Omicron variants under development have significantly heightened worldwide pandemic concerns. In this review, the authors will outline the molecular features and efficacy of vaccination, highlight possible omicron impacts on scientific research, and provide precautions, procedural guidelines for organizing scientific meetings during a pandemic

SEVERE ACUTE RESPIRATORY SYNDROME CORONAVIRUS TYPE 2 OMICRON VARIANT OUTBREAK IN INDIA: TIME TO ALERT

Early 2022 saw an outbreak of the coronavirus severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) variant known as Omicron, which has become more contagious than the previous variants of concern alpha, beta, and gamma variants, and it shares many mutations. Still, so far, Omicron transmission has exceeded many borders worldwide compared to other kinds of SARS-CoV-2; there has been a significant increase in the number of confirmed cases globally, and it is re-emerging currently in India. The World Health Organization, the Centers for Disease Control and Prevention (CDC), the Ministry of Health and Family Welfare, and other research institutions, as well as worldwide international press media provided data on “Omicron” outbreaks in India. Our review recorded information about the prevalence and clinical characteristics of the Omicron variant of SARS-CoV-2 from November 24, 2021, to January 17, 2022. Our highlights will talk about its global transmission, characteristics, and impact on vaccine efficiency, and possible strategies to prevent and overcome the spread of the Omicron variant.</jats:p
